Error Handling In ASP

[Erencans]

Hi to all,
I want to error handling in ASP. But i think that ASP is not enough for
error handling. I have got two chance.
1. I can prapare an error page and control throught IIS.
2. I can use on error resume next.

For 1. This is a general handling. I want to handle local error. Maybe i do
special thing when error occured.
For 2. I have to write alot of lines code. I have to control every line.

I wait your opinion.
Thanks alot.

Note: I must use ASP.

What do you mean by local error? What's the question here?

I mean that for example i start a database transaction so an error occured. I
want to rollback transaction with error handling. i can do it in error page
but i think it is not a good way. Because i have to control that is there a
connection and transaction.Maybe i don't want rollback transaction every
error. Like this...

I hope i can explain what i mean.

This is not an all or nothing option.

IMO use
http://support.microsoft.com/default.aspx?scid=kb;en-us;224070 (this is 1.)

It will allow to trap all errors you are not prepared to handle.

I would use 2 on very rare occasion only if I have no way to do it otherwise
(for example you could test for file existance instead of trapping the error
because the file is not available or checking a divider before a division
instead of trapping a divide by zero error). Also 2 is usefull only if your
application could do something about it and if you have a good idea of what
could goes wrong.

So in short I would use option #1 and would perhaps have one or two (or
zero) on error resume next line in the whole application...

How about rolling back the transaction at the database level instead of the
application level? What kind of database?

I connect to SQL Server via ADO. I'll use transaction with ADO.

Thanks alot for opinions. Why don't ASP support label defitiniton like VB.
Like On Error Goto label... It could very useful for me.

Don't know but I'm not really a great "on error" fan. What is the exact
siutation you are facing ? What is the error you would like to handle ? How
frequent it is ?

Start at least with option #1. It will at least allows to see all errors
(the error page could mail you error details).
